Technology-driven Industry 4.0 (I4.0) paradigm combined with human-centrism, sustainability, and resilience orientation, forms the Industry 5.0 (I5.0) paradigm, providing support for the workforce and enabling the Operator 4.0 (O4.0) approach. The I5.0 focuses can face unforeseen challenges, as the applicability and readiness of I4.0 solutions are still not well discussed in the literature. Therefore, structuring existing knowledge of O4.0 to prepare for the smooth transition toward Operator 5.0 (O5.0) is crucial. A systematic literature review is performed in the Scopus database, considering ...

[EN] A lean supply chain (LSC) is a set of organizations directly linked by upstream and downstream value streams between processes that work collaboratively to reduce costs and waste. Currently, supply chains (SCs) have been put to the test as the world has had to face a series of unprecedented disruptions in demand and supply caused by the COVID-19 pandemic. In this paper, a detailed study of constructs and multistructural components was carried out to develop a conceptual reference model that merges Industry 4.0 (I4.0) digital technologies with lean manufacturing tools to reduce waste and m...

Lignocellulosic biomass is a promising alternative to petroleum oil for producing energy and chemicals, owing to its abundance and sustainability. In the past decades, extensive research has applied a wide range of thermo-chemical technologies for converting biomass into value-added products. Among them, hydrothermal liquefaction (HTL) is regarded to be one of the most effective techniques to produce bio-fuels and bio-based chemicals. However, there are still several technical barriers that must be addressed before the industrialization of HTL technology. Although many previous reviews have su...

Mechanical oil recovery (i.e., booming and skimming) is the most common tool for oil spill response. The recovered fluid generated from skimming processes may contain a considerable proportion of water (10 % ~ 70 %). As a result of regulatory prohibition on the discharge of contaminated waters at sea, vessels and/or storage barges must make frequent trips to shore for oil-water waste disposal. This practice can be time- consuming thus reduces the overall efficiency and capacity of oil recovery. One potential solution is on-site oil-water separation and disposal of water fraction at sea. Howeve...

The development of clean and efficient energy conversion and storage systems is becoming increasingly vital as a result of accelerated global energy consumption. Solid oxide fuel cells (SOFCs) as one key class of fuel cells have attracted much attention, owing to their high energy conversion efficiency and low emissions. However, some serious problems appeared because of the scorching operating temperatures of SOFCs (800–1000 °C), such as poor thermomechanical stability and difficult sealing, resulting in a short lifespan and high cost of SOFCs. Therefore, lowering the operating temperature of...

Prompted by the increasing number of electrochemical biosensors reported in the literature, a wide range of lab-made potentiostats have been developed by researchers in recent years. While these devices are less costly than their commercial counterparts, they are typically single-plex and rely on non-integrated sample preparation or signal actuation devices. To address these limitations, we have designed a portable and fully integrated platform for point-of-care (PoC) electrochemical readout and actuation. This device performs standard voltammetric techniques and is controlled remotely by an a...

Despite significant changes in management of labor and delivery over the past few decades, operative vaginal birth remains an important component of modern labor management, accounting for 3.3% of all deliveries in 2013 (1). Use of obstetric forceps or vacuum extractor requires that an obstetrician or other obstetric care provider be familiar with the proper use of the instruments and the risks involved. The purpose of this document is to provide a review of the current evidence regarding the benefits and risks of operative vaginal birth.

Current paediatric anaesthetic fasting guidelines have recommended conservative fasting regimes for many years and have not altered much in the last decades. Recent publications have employed more liberal fasting regimes with no evidence of increased aspiration or regurgitation rates. In this first solely paediatric European Society of Anaesthesiology and Intensive Care (ESAIC) pre-operative fasting guideline, we aim to present aggregated and evidence-based summary recommendations to assist clinicians, healthcare providers, patients and parents. We identified six main topics for the literature...

Abstract The modern approach to m ‐form global symmetries in a d ‐dimensional quantum field theory (QFT) entails specifying dimension topological generalized symmetry operators which non‐trivially link with m ‐dimensional defect operators. In QFTs engineered via string constructions on a non‐compact geometry X , these defects descend from branes wrapped on non‐compact cycles which extend from a localized source / singularity to the boundary . The generalized symmetry operators which link with these defects arise from magnetic dual branes wrapped on cycles in . This provides a systematic way to...

We study the pricing and return policy decisions of an omnichannel retailer serving customers who differ in how they realize their uncertain valuation for a product—by inspecting in store before purchase or by purchasing online and possibly returning misfit products. Customers may return misfit products either to stores for a full refund or online as per the firm’s return policy. We model prices to be identical across channels, allow crosschannel returns, and endogenize customers’ purchase and return decisions, capturing typical features of an omnichannel setting. Our analysis helps explain wh...
